New build mastic for homes and businesses in Elmhurst
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. We work on plot handovers, windows & doors and kitchens, and common reasons people get in touch are internal frame sealant that has split and joints pulling apart as timber shrinks.
In and around Elmhurst, floors range from older timber boards to tiles and newer finishes, each moving in its own way. The sealant at skirtings and thresholds has to suit the floor it meets.
A 12-month guarantee comes as standard, so you are covered after we’ve gone.

What else we do in Elmhurst
How it works
There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours for most snagging lists, longer for a run of plots, including the tidy-up. A visit to Elmhurst is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
How to prepare
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height

Different surfaces, different methods
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens, food-safe where it’s needed.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
What affects the quote in Elmhurst
You’ll get a clear quote before any work starts. It’s based on:
- The old material and how stubborn it is
- The amount of work
- Access and height
- Mould in or behind the old joints
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or email us and we will give you an honest view and a quote.
What to tell us for a quote
To make quoting easier, let us know:
- Pictures of the joints, sent by email
- The problem you’ve noticed
- Whether it has been sealed before
- Where the property is
For a quote, ring 0345 464 0079 or send us an email with the location and a short description of the problem. You’ll have a clear quote before any work starts.
Why it’s worth doing now in Elmhurst
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Around Elmhurst, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Elmhurst questions
Is Elmhurst in your area for new build mastic?

Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected.
What does new build mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.
Is it normal for sealant to crack in a new home?
There are usually two causes: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Do you work for developers?
Yes. We seal plots to the developer’s programme ready for handover. Tell us the plots and the joints involved and we will quote.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
What sealant work cannot fix
To be straight with you, there are a few things sealant won’t fix:
- Deciding who is responsible under a builder’s warranty
- Cracking that points to a structural problem
- Leaks from pipes, valves or wastes, which need a plumber
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.
